To RMA broken hardware is a matter of personal choice. Some people are heavily against it, some people just don't care if they'll have to pay 10€ more next time, because they'll just buy another (cheaper) card. The world is filled with this kind of dilemma's, I don't see why this one would be more bad than, for instance, download one MP3 file or throw away a little bit of food because you're not hungry anymore or drive a bit faster on the freeway.

Always be responsible for your own actions, if the accident happened because of your fault then you should be the one to blame, not others. I don't know if it will really drive up the price, but at least have respect to the company you bought your goods from.

If the mayonnaise was mixed up with ketkchup at someone's home, to 'improve' its taste, would RMA be an issue then?
